[AArch64] PR target/68129: Define TARGET_SUPPORTS_WIDE_INT

	PR target/68129
	* config/aarch64/aarch64.h (TARGET_SUPPORTS_WIDE_INT): Define to 1.
	* config/aarch64/aarch64.c (aarch64_print_operand, CONST_DOUBLE):
	Delete VOIDmode case.  Assert that mode is not VOIDmode.
	* config/aarch64/predicates.md (const0_operand): Remove const_double
	match.

	* gcc.dg/pr68129_1.c: New test.
